Asgaros Forum < 3.2.0 - SQL Injection
Asgaros Forum for WordPress versions prior to 3.2.0 is vulnerable to unauthenticated SQL injection through the asgarosforum_unread_exclude cookie. The cookie is JSON-decoded and its object keys are imploded into a NOT IN() clause without sanitisation. The vulnerable query only runs while rendering the forum page, so the payload must be sent there rather than to the site root.
